NAME
gdalinfo - gdalinfo lists information about a raster dataset
SYNOPSIS
gdalinfo [--help-general] [-mm] [-stats] [-hist] [-nogcp] [-nomd]
[-norat] [-noct] [-nofl] [-checksum] [-proj4]
[-listmdd] [-mdd domain|`all`]*
[-sd subdataset] datasetname
DESCRIPTION
The gdalinfo program lists various information about a GDAL supported raster dataset.
- -mm
- Force computation of the actual min/max values for each band in the dataset.
- -stats
- Read and display image statistics. Force computation if no statistics are stored in an image.
- -approx_stats
- Read and display image statistics. Force computation if no statistics are stored in an image. However, they may be computed based on overviews or a subset of all tiles. Useful if you are in a hurry and don't want precise stats.
- -hist
- Report histogram information for all bands.
- -nogcp
- Suppress ground control points list printing. It may be useful for datasets with huge amount of GCPs, such as L1B AVHRR or HDF4 MODIS which contain thousands of them.
- -nomd
- Suppress metadata printing. Some datasets may contain a lot of metadata strings.
- -nrat
- Suppress printing of raster attribute table.
- -noct
- Suppress printing of color table.
- -checksum
- Force computation of the checksum for each band in the dataset.
- -listmdd
- (GDAL >= 1.11) List all metadata domains available for the dataset.
- -mdd domain
- Report metadata for the specified domain. Starting with GDAL 1.11, 'all' can be used to report metadata in all domains
- -nofl
- (GDAL >= 1.9.0) Only display the first file of the file list.
- -sd subdataset
- (GDAL >= 1.9.0) If the input dataset contains several subdatasets read and display a subdataset with specified number (starting from 1). This is an alternative of giving the full subdataset name.
- -proj4
- (GDAL >= 1.9.0) Report a PROJ.4 string corresponding to the file's coordinate system.
The gdalinfo will report all of the following (if known):
- •
- The format driver used to access the file.
- •
- Raster size (in pixels and lines).
- •
- The coordinate system for the file (in OGC WKT).
- •
- The geotransform associated with the file (rotational coefficients are currently not reported).
- •
- Corner coordinates in georeferenced, and if possible lat/long based on the full geotransform (but not GCPs).
- •
- Ground control points.
- •
- File wide (including subdatasets) metadata.
- •
- Band data types.
- •
- Band color interpretations.
- •
- Band block size.
- •
- Band descriptions.
- •
- Band min/max values (internally known and possibly computed).
- •
- Band checksum (if computation asked).
- •
- Band NODATA value.
- •
- Band overview resolutions available.
- •
- Band unit type (i.e.. 'meters' or 'feet' for elevation bands).
- •
- Band pseudo-color tables.
